Description: The function of this variable is to summarize the information concerning the presence of the module and the module type for each slot of the hub. The second octet will contain '4' to indicate that what follows is an octet string. The third octet will contain '1' since each module type will be contained in 1 octet. Octets 4 through 4+n (n=number of slots) will contain the module type for the corresponding slot. The information is coded as follows: First Octet: number of slots Second Octet: SNMP Type of information: Integer = 2, OctetString = 4. Third Octet: length of each field Fourth Octet: if no module in slot #1 then '0', else the module type i.e, the integer corresponding to promModuleType. Last Octet: the module type corresponding to the last slot in the hub.
